18 Floating Point – FNC110 to FNC139
18.4 FNC116 – ESTR / Floating Point to Character String Conversion
- When the number of digits of the decimal part is set to any value other than "0", "2EH (.)" is automatically stored
in "specified number of digits of decimal part + 1"th digit.
When the number of digits of the decimal part is "0", "2EH (.)" is not stored.
- When the total number of digits subtracted by the digits for sign, decimal point and decimal part is larger than the
integer part of the binary floating point data, "20H (space)" is stored between the sign and the integer part.
- "00H" or "0000H" is automatically stored at the end of the converted character string.
3. In the case of exponent format
• The total number of digits which can be specified by +1 is as follows (24 digits maximum):
When the number of digits of the decimal part is "0" Total number of digits ≥ 6
When the number of digits of the decimal part is any value other than "0" Total number of digits ≥ (Number of digits
of decimal part + 7)
